WATER-HEATER.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application iiled June 20,1904. Serial No. 213,226.

'o all whom it may concern:

Be it known that I, WILLIAM G. BURR, a citizen of the United States,residing at Kenosha, in the county of Kenosha and State of Visconsin,have invented certain new and useful Improvements in Water-Heaters, ofwhich the following is a specification.

'The object of this invention is the production of an improvedwater-heater adapted to be operated in connection with an ordinaryfurnace.

In the accompanying drawings, Figure '1 is a vertical central sectionthrough a furnace, showing this improved water-heater applied thereto.Fig. 2 is a horizontal central section through said water-heater.

A refers to a furnace of ordinary construction, and B to the gratetherein.

In the construction of a water-heater embodying the features of thisinvention I provide an integral hollow body portion 1, comprising thetop plate 2, the bottom plate 8, and the peripheral side walls 4. At oneside of the body portion is formed a tubular internally-screw-threadedboss 5, the bore of which communicates with the interior of said bodyportion, said boss being adapted to receive theexternally-screw-threaded end of the inlet-pipe 6. In practice thisinlet-pipe extends through a suitable opening in the wall of theJfurnace A and provides a means for supporting the heater at a properdistance above the grate B.

Centrally within the body portion 1 is a curved deflecting-plate 7,extending between the top plate 2 and the bottom plate 3 and providingan opening 8 between its ends. The deiiecting-plate 7 is formed integralwith the body portion 1 or is secured therein in any other suitable way.An outlet-opening 9 in the top plate 2 coincides in position with thedeflector 7 and is adapted to receive the end of the outlet-pipe 10.

Flues 11 for the passage of smoke and iiame extend vertically throughthe body portion 1 and are preferably formed integral therewith. Theseilues also serve to strengthen the structure by uniting the top plate 2and the bottom plate 3.

Upon the under side of the bottom plate 3 are formed integraldownwardly-extending hollow bosses 12, closed at their lower ends, saidbosses communicating with the interior of the body portion 1 and servingto increase the heating-surface of said body portion.

In operation the current of water flowing into the heater through theinlet-pipe 6 strikes the deiiector 7 and is deflected to all parts ofthe heater, iinally passing through the openings 8 and 9 into theoutlet-pipe 10. The gaseous products of combustion pass upwardly aroundthe sides of the heater and through the flues 11. Being spread out in acomparatively thin sheet and brought into proximity with the iire atnumerous points by means of the bosses 12 and the flues 11, the waterflowing through the body portion 1 is quickly raised to a hightemperature.

I claim as my invention- 1. In a water-heater, in combination, a hollowbody portion having an inlet in one of its sides and a central outlet inits upper portion; and a curved deflecting-plate partially surroundingsaid outlet, the convex side of said plate facing said inlet, a spacebeing provided between the ends of said plate through which the heatedwater passes before reaching the outlet.

2. In a water-heater,` in combination, a hollow body portion in diskform, comparatively thin in cross-section, having'an inlet in one of itssides, a central outlet in its upper portion, fiues extending throughsaid body portion and a plurality of hollow bosses upon its under sidecommunicating with the interior of said body portion; and a deflectorcomprising a curved plate partially surroundin said outlet and extendingfrom top to bottom of the body portion, said plate being locatedopposite said inlet, with its convex side facing said inlet and adaptedto break up the stream of water entering therethrough, the waterentering the space within said curved plate through the space betweenthe adjacent ends of the said plate, and passing through the outlet.
